  • Speedy development has been witnessed in communication technologies and the adoption of the Internet across the world. Information dissemination is the primary goal of these technologies. One of the rapidly developing nations in the Middle East is Saudi Arabia, where the use of communication technologies, including mobile and Internet, has drastically risen in recent times. These advancements are relatively new to the region when contrasted to developed nations. Thus, offenses arising from the adoption of these technologies may be new to Saudi Arabians. This study examines cyber security awareness among Saudi Arabian citizens in distinct settings. A comparison is made between the cybersecurity policy guidelines adopted in Saudi Arabia and three other nations. This review will explore distinct essential elements and approaches to mitigating cybercrimes in the United States, Singapore, and India. Following an analysis of the current cybersecurity framework in Saudi Arabia, suggestions for improvement are determined from the overall findings. A key objective is enhancing the nationwide focus on efficient safety and security systems. While the participants display a clear knowledge of IT, the surveyed literature shows limited awareness of the risks related to cyber security practices and the role of government in promoting data safety across the Internet. As the findings indicate, proper frameworks regarding cyber security need to be considered to ensure that associated threats are mitigated as Saudi Arabia aspires to become an efficient smart nation.

  • Fashion trends are actively disseminated through social media, which influences both their propagation and consumption. This study explored how users perceive subversive basic fashion in social media videos, by examining the associated concepts and characteristics. In addition, the factors contributing to the style's social media dissemination were identified and its distinctive features were analyzed. Through text mining analysis, 80 keywords were selected for semantic network and CONCOR analysis. TF-IDF and N-gram results indicate that subversive basic fashion involves transformative design techniques such as cutting or layering garments, emphasizing the body with thin fabrics, and creating bold visual effects. Topic modeling suggests that this fashion forms a subculture that resists mainstream norms, seeking individuality by creatively transforming the existing garments. CONCOR analysis categorized the style into six groups: forward-thinking unconventional fashion, bold and unique style, creative reworking, item utilization and combination, pursuit of easy and convenient fashion, and contemporary sensibility. Consumer actions, linked to social media, were shown to involve easily transforming and pursuing personalized styles. Furthermore, creating new styles through the existing clothing is seen as an economic and creative activity that fosters network formation and interaction. This study is significant as it addresses language expression limitations and subjectivity issues in fashion image analysis, revealing factors contributing to content reproduction through user-perceived design concepts and social media-conveyed fashion characteristics.

  • 현재의 무선 센서네트워크는 다중 목적지 그룹에 동일한 interest를 전파함에 있어서 목적지 그룹별로 개별적인 interest 전송 경로를 사용한다. 이러한 데이터 전송기법은 동일한 정보를 여러 번에 걸쳐 전송함으로써 네트워크에 불필요한 트래픽을 증가시키고, 에너지 자원이 빈약한 센서네트워크의 네트워크 생명을 감소시키는 원인이 된다. 범용 센서네트워크에서 동일한 interest를 네트워크상의 다중 목적지에 전송하는 경우 공유경로의 사용을 통하여 네트워크 트래픽을 감소시킬 수 있다. 따라서 본 논문에서는 센서노드의 위치 정보를 기반으로 싱크노드로부터 복수개의 목적지 그룹까지 데이터를 전송함에 있어서 공유경로를 사용하여 데이터의 전송 경로를 최적화하는 기법을 제안한다. 제안 방우의 성능번상은 시걸친이해에 의해 불증하필으요, 에러 경로 최대 30%까지 감소하필다.

  • The paper presents a method of assessing the adequate tapaclty of photovoltaic generation systems for public buildings based on analysis of load variation patterns of customers. When PV systems are installed for supplying power for the customer load, reverse power relay is required by the guideline to be installed at the point of common coupling with the power network. The suggested method analyzes daily, weekly and monthly load demand of the customer that Irishes PV system installation, and determines the appropriate rating of the PV system for preventing PV generation from exceeding the customer demand. This work is expected to support renewable energy dissemination projects of public organizations.

  • 센서 네트워크는 수많은 센서 노드로 구성된 센서 필드와 센서 노드로부터 데이터를 수집하는 싱크 노드로 이루어져 있으며, 유비쿼터스에서 중요한 부분을 차지하고 있다. 현재 까지 연구 되어온 센서 네트워크에 대한 연구의 중요한 이슈중 하나는 센서 노드가 제한 자원을 가지기 때문에 한정된 에너지를 최대한으로 사용하여 네트워크의 수명을 연장하는 것이다, 그러나 기존 연구 대부분이 고정된 상태의 싱크 노드를 고려하기 때문에 본 연구에서는 이동성을 가진 싱크노드가 다수가 존재하는 경우 센서 필드에서 수집된 데이터가 이동 싱크 노드까지 끊임없이 전송 될 수 있으며 효율적인 데이터 보급을 제공하는 계층적 라우팅 프로토콜을 제안한다.

  • 센서 네트워크는 관심이 있는 현상을 관찰하기 위해서 관찰지역 내에 뿌려진 센서 노드들로 구성된다. 센서 네트워크를 구성하는 각 센서 노드들의 수명은 전체 센서 네트워크 수명에 많은 영양을 준다. 하나의 센서 노드가 수명을 다 했을 때 이는 센서 네트워크의 분할을 가져 올 수도 있다. 그러므로 모든 센서 노드들이 공평하게 다 같이 오래 사는 것이 전체 센서 네트워크의 수명을 연장하는 것이다. 이 논문에서 우리는 클러스터 기반의 에너지 효율적인 라우팅 프로토콜(Cluster-eased Power-Efficient Routing Protocol CBPER)을 제안하였다. 제안된 프로토콜은 여러 개의 유동성 싱크 노드를 가진 센서 네트워크에서 에너지 효율적인 데이터 전송을 지원하며 효율적인 라우팅을 위해서 각 센서 노드의 위치정보를 기반으로 만든 그리드 구조를 이용한다. 제안된 프로토콜의 성능을 평가하기 위해서 두 계층 데이터 전송 라우팅 (Two-Tier Data Dissemination Routing: TTDD) 프로토콜과 비교를 하였다. 실험결과는 CBPER 프로토콜이 TTDD 라우팅 프로토콜 보다 좀 더 에너지 효율적이라는 결과를 보여 준다.

  • In this paper, we propose a grid-based efficient routing protocol for a mobile sink in wireless sensor networks. In the proposed protocol, the network is partitioned into grids and each grid has a grid head. For the efficient routing to a mobile sink, the proposed protocol uses a mobile sink representative node to send the data to a mobile sink and grid heads are used as a mobile sink representative node. Furthermore, the proposed protocol uses nodes in the boundary of the center grid as position storage nodes. The position storage nodes store the position of a mobile sink representative node and provide source nodes with it for data delivery. With these features, the proposed protocol can reduce a lot of overhead to update the position information and improve the delay of data delivery to a mobile sink. The proposed protocol performs better than other protocols in terms of the delay and the energy consumption per node in the performance evaluation.
